“Think of the TEK 2.0 as a security blanket that tells you where your dogs are, instantly, at any given time during a hunt. As good as some beeper collars may be, that’s an advantage they can’t even being to match.”Ben Garcia, Professional Dog Trainer
The tone function on SportDOG Brand® remote trainers is a versatile button. Some folks like to use the tone button as a warning sound for their dog before delivering stimulation. Another use would be to tone your dog each time it gives you a positive response to a command. Or, training the dog to recall, or "come" when the tone button is pressed.
